How Surepass US Address Verification API Works

The Address Verification API validates each address at the point of entry, flags missing or invalid components and returns a match result before a package ships or a customer is onboarded.
  • Input: The user needs to provide the address. This includes the details like street name, apartment number, city, state and ZIP code.
  • The API checks every address and then you get a clear result whether the address exists.
  • Output: Receive a structured response from the API.

How U.S. Address Validation API Works

What are the features of US Address Validation API?

Our API helps you check, fix and standardize every USA address in real time, by your own system.
Check Deliverability Instantly
Find out whether an address is deliverable, undeliverable or needs more details, before you ship, mail or approve an order. These checks happen in real time.
Address Standardization
Every address is converted into one postal format. The street suffix, directionals (like N or SW), capitalization and ZIP code all follow the same pattern to keep your records consistent.
Auto-Correction
Common mistakes like misspelled street or city names, wrong ZIP codes and missing directionals don’t stop the API checks. The API fixes it and returns the correct address.
Missing Unit Detection
Find out when an address needs an apartment, suite or floor number (basically the secondary address).
Residential or Commercial Check
Know whether an address is residential or commercial (RDI), so you can charge accordingly (for carrier surcharges and shipping rates).

Benefits of Verifying Addresses with the API

When you use Surepass Address Verification API there is no need to do manual address checks or fix errors after a delivery goes wrong, the API handles it upfront.
Fewer Failed Deliveries
Wrong, incomplete or non-existent addresses are caught at the point of entry, so more orders reach the customer on the initial attempt.
Lower Shipping and Mailing Costs
With a verified and correct address, there will be fewer returns, reduction of re-shipments and correction fees and less money is lost on every order and every campaign.
Clean and Consistent Data
Addresses are saved in one standard format over time. With this standardisation, duplicate addresses are easier to spot and your CRM, ERP and billing data stay clean.
Faster Onboarding
Results come back in real time, so checkout, sign-up and approvals are never delayed or stopped.

Campaigns, offers and notices will reach real customers when they have valid addresses. The marketing team would spend less as they would know what incomplete or wrong addresses are.
